  • Patent number: 6811917
    Abstract: A conductive, moldable composite material for the manufacture of electrochemical cell components comprising a thermosetting resin system and conductive filler wherein the thermosetting resin composition comprises: (1) a polybutadiene or polyisoprene resin; (2) an optional functionalized liquid polybutadiene or polyisoprene resin; (3) an optional butadiene- or isoprene-containing copolymer; and (4) an optional low molecular weight polymer. In a preferred embodiment, the conductive moldable composite material is used to form a bipolar plate, current collector or other electrochemical cell component. Articles made of the conductive moldable composite material are resistant to chemical attack and hydrolysis, have excellent mechanical strength and toughness, have a volume resistivity of about 0.116 ohm-cm or less and preferably about 0.04 ohm-cm or less and a thermal conductivity of at least about 5 watts/meter ° K.

  • Publication number: 20020155333
    Abstract: A component for an electrochemical cell comprises a thermally and electrically conductive core with an active area substantially covered by an electrically and thermally conductive polymeric composite, wherein the conductive polymeric composite is adhered to the core by an adhesion promoter. The electrically conductive polymeric composite preferably comprises a thermosetting polybutadiene- or polyisoprene-based resin system and an electrically conductive filler. The component is resistant to chemical attack and hydrolysis, and has excellent mechanical strength and toughness. Components may be manufactured having a volume resistivity of about 0.500 ohm-cm or less and a thermal conductivity of at least about 5 watts/meter ° K,. In addition, the component is economical to produce due to inexpensive starting materials as well as the use of conventional processing equipment.
